I currently have a problem with editing an interlaced mpeg2 source and exporting it to DVD. I plan to start a separate thread thread for this. There is a suggestion on ffmpeg which might help me:
http://ffmpeg.mplayerhq.hu/faq.html#SEC22 1.21 Interlaced video looks very bad when encoded with ffmpeg, whats wrong? You should use '-flags +ilme+ildct' and maybe '-flags +alt' for interlaced material, and try '-top 0/1' if the result looks really messed-up. Kdenlive enables to create a custom encoder setting, where you can add any export settings recognized by libavcodec (the encoder) - which is excellent - but the format of ffmepg and libavcodec seems to differ. So how I can add the suggested flags? I have tried: "format=dvd vcodec=mpeg2video acodec=ac3 ... flags=+ilme+ildct" and "format=dvd vcodec=mpeg2video acodec=ac3 ... flags=+ilme+ildct" and "format=dvd vcodec=mpeg2video acodec=ac3 ... flags=+ilme+ildct+alt" and "format=dvd vcodec=mpeg2video acodec=ac3 ... flags=+ilme+ildct top=0/1" Encoder made no complaints - is this enough confirmation that parameters where recognized? - and gave me 3 example outputs. But all three seems to completely the same, sharing the same problem. Any help appreciated Espinosa
